Application March 16, 1932, Serial No. 599,192

4 Claims. (01. 2i659) Rolls of paper, which are heavy, for example the rolls of printing paper supplied tonewspapers, when handled in loading, unloading or storing, are, because of their weight, trundled or rolled over the ground on an end. Such trundling places a great strain on the trundling edge of the roll,

and more or less crushes and tears away the outer windings of the sheet composing the roll, and so causes a waste and loss which frequently is considerable.

To protect the roll ends against such damage and waste, the ends are wrapped with a band or" strong paper, but this protector-wrapping is insufficient to prevent said damage, because the heavy weight imposed on the trundled roll end tends to strip off the protective covering band, or mash the edge of the roll; and frequently does both.

I have discovered that an .efficient and convenient way of protecting the edge of the roll end is to place over it a protector boot. This'boot must be adapted to be readily secured on the roll end, and besides, must be adapted to provide an exterior buffer-protrusion; and preferably should provide an interior annular space about the edge of the inclosed roll end, so as to prevent the transmission of any stresses from the sole or leg of the boot to the edges of the sheets composing the roll, while the roll is being trundled on its end.

Where the boot is made of a substantially rigid material, paper, for example, the providing of the said exterior bufier protrusion will give sufiicient protection without said interior space. But if no interior space is provided about the edge, and the boot leg is made of material more or less yielding, in consequence the sole of the boot will bear firmly on the edge of the roll, then any stress imposed on the sole of the boot, in the trundling of the roll on end, would most likely be transmitted to the edges of the outer windings of the sheet composing the roll, and cause them to be more or less mashed, and require these outer windings to be stripped ofi and wasted.

Furthermore, the sole of the boot should be provided with a heel so arranged that the trundling of the roll on an end as mentioned will not transmit any strain to the edge of the roll end. Preferably this heel should be located inward from the circumference of the roll end, so that no stress will be imposed on the edge of the roll end, in tilting and trundling the roll on end. When the heel is arranged as mentioned, then i the stresses transmitted to the roll end would be located a substantial distance inward of the circumference of the roll end, thus at a point where buffer for the roll ends.

the solidity of the winding of the sheet making up the roll is well able to stand such. stresses without injury to the edges of the outer sheets composing the roll end.

My protector boot further serves as a protective In the placing of a roll close to another roll it frequently happens that the roll being moved into place strikes against another roll with such force as to damage the latter. By my protective boot such damage is avoided, by the resilient buffer protrusion provided about the inclosed edge of the roll.

My protective boot is preferably made of elastic material, specifically rubber, and in that way it is adapted to be placed on rolls of varying diameters.

terial secures the upper part of the boot leg 5 firmly in place on the roll end.

By placing my protective boot on both-ends of rolls of paper, chafingrand resulting injury and damage frequently incurred in the transporta tion of rolls is prevented.

Furthermore, by making my protective boot with a sole that extends all the way across the bottom of the boot; theroll end onwhich my protective boot is aiiixed is effectivelyprotected against moisture on the ground on which the roll is stood. v

Where the sole of the boot extendsall the way across it may be provided with a knob-like protrusion at the center on which the roll, when stood on end, may be tilted sufficiently to facilitate the picking up or" the roll by a hand-truck.

Furthermore, when using my protector boot,

only a very light paper wrapping or covering of the roll ends is required, in that way saving both in time and material over the present heavy wrapping of the roll ends.

My invention is susceptible to modifications in details of construction and the arrangement of its elements.

I attain the foregoing objects and incidental features in the protector-boot hereinafter described, referencebeing had to the accompanying drawings. 7

In the drawings:

Fig. 1 shows, partly in section and partly in elevation, the lower end of a roll of paper on which my protector-boot is placed. This figure further shows a knob inserted in the end of the hollow core of the roll, to tilt the roll slightly, and thus i much greater diameter:
